1 Rep Max Weighted Pull Ups Calculator

This calculator determines the maximum extra weight that you can attach to yourself and perform 1 pull up (one rep max). Our 1 RM weighted pull ups calculator uses 2 main inputs:

  • Your bodyweight
  • The maximum number of pull ups you can do with no attached weights

How to use the 1 RM Weighted Pull Ups Calculator

The calculator uses your bodyweight and rep count for unweighted pull ups and applies it through a special formula that then determines your approximate 1 RM weighted pull up.

  1. Enter your bodyweight in either imperial (lbs) or metric (kg)
  2. Enter the maximum number of bodyweight pull ups you can do

As an example, if you weighed 180 pounds and could perform 10 body weight pull ups, then enter:

  • Your bodyweight: 180
  • Max reps of unweighted pull ups: 10

This would give you an answer of 50 lbs!

Please bear in mind that this pull ups calculator only gives an approximation. It’s relatively accurate for bodyweight reps of up to 30 but anything after that, the calculation becomes less reliable.

Give it a try and post your calculated numbers in the comments below and let us know how accurate (or inaccurate) it was!
